Keratin fibre dyeing composition comprising a particular aminosilicone

ABSTRACT

The disclosure relates to a composition for dyeing human keratin fibres, such as hair, comprising in a cosmetically acceptable medium at least one direct dye or at least one oxidation dye and at least one aminosilicone.  
     The disclosure further relates to dyeing devices and methods employing the composition.

[0001] The present disclosure relates to a composition for dyeing human keratin fibres, such as hair, comprising at least one direct dye or oxidation dye and at least one aminosilicone.

[0002] In principle, there are two methods of dyeing human keratin fibres, such as hair: direct dyeing and oxidation dyeing. Direct dyeing employs direct dyes and/or pigments that are coloured molecules. These direct dyes and/or pigments give the fibres a temporary colour, which fades after several shampooings. Direct dyeing may be carried out in the presence or absence of oxidizing agents. Oxidation dyeing employs oxidation dye precursors and an oxidizing agent, and imparts to the fibres a colour that is longer-lasting than direct dyeing. The use of an oxidizing agent may involve a certain degree of degradation of the keratin fibre.

[0003] An increase in the frequency of shampooing may lead to greater degradation of a keratin fibre dyeing between applications.

[0004] Consequently, there exists a need to improve the durability of the direct dyeing or oxidation dyeing, especially with respect to shampooing.

[0005] After considerable research, the inventors have discovered, quite unexpectedly and surprisingly, that the use of a composition comprising at least one direct dye or at least one oxidation dye and at least one aminosilicone allows at least one problem described above to be solved.

[0006] The composition allows the condition of the fibre to be improved. Improving the condition of the fibre may mean, for example, reducing the porosity or the alkaline solubility of the fibre and improving cosmetic properties, such as smoothness, softness and ease of disentangling and styling.

[0007] This effect is remanent, e.g., durable.

[0008] The porosity is measured, for example, by the binding of 2-nitro-para-phenylenediamine at 0.25% in an ethanol/pH 10 buffer mixture (volume ratio 10/90) at 37° C. and a pH of 10 in 2 minutes.

[0009] The alkaline solubility corresponds, for example, to the loss in mass of a sample of 100 mg of keratin fibres under the action of decinormal sodium hydroxide solution at 65° C. for 30 minutes.

[0010] This discovery partially forms the basis of the present disclosure.

[0011] An embodiment provides a composition for dyeing human keratin fibres, such as hair, comprising in a cosmetically acceptable medium at least one direct dye or at least one oxidation dye, and further comprising at least one aminosilicone chosen from formulae (I) and (II), these formulae being described below.

[0012] Another embodiment provides a ready-to-use composition for dyeing human keratin fibres comprising at least one direct dye or at least one oxidation dye and at least one aminosilicone chosen from formulae (I) and (II), these formulae being described below, and at least one oxidizing agent.

[0013] A “ready-to-use composition” means a composition intended for application as it is to the keratin fibres, e.g., it may be stored before use or may result from the extemporaneous mixing of at least two compositions.

[0014] Another embodiment provides a method of dyeing human keratin fibres, such as hair, comprising applying to the fibres at least one colouring composition comprising, in a cosmetically acceptable medium, at least one direct dye and at least one aminosilicone chosen from formulae (I) and (II).

[0015] Another embodiment provides a method of dyeing human keratin fibres, such as hair, comprising applying to the fibres at least one colouring composition comprising, in a cosmetically acceptable medium, at least one direct dye or at least one oxidation dye and at least one aminosilicone chosen from formulae (I) and (II). The colour may be developed at alkaline, neutral or acidic pH by means of at least one oxidizing composition comprising at least one oxidizing agent. The at least one oxidizing composition may be mixed at the time of use with the at least one colouring composition, or the at least one colouring composition and the at least one oxidizing composition may be applied sequentially without rinsing in between applications.

[0016] A further embodiment provides for multi-compartment a dyeing device or kit.

[0017] In an embodiment, a multi-compartment kit may comprise a first compartment comprising a composition comprising, in a cosmetically acceptable medium, at least one direct dye or at least one oxidation dye and at least one aminosilicone chosen from formulae (I) and (II). A multi-compartment kit may comprise a second compartment comprising a composition comprising, in a cosmetically acceptable medium, at least one oxidizing agent.

[0018] In another embodiment, a multi-compartment device may comprise a first compartment comprising a composition comprising, in a cosmetically acceptable medium, at least one direct dye or at least one oxidation dye, a second compartment comprising a composition comprising, in a cosmetically acceptable medium, at least one oxidizing agent, and a third compartment comprising a composition comprising, in a cosmetically acceptable medium, at least one aminosilicone chosen from formulae (I) and (II).

[0019] At least one other characteristic, aspect, subject matter and advantage of the invention will appear more clearly to a person of ordinary skill in the art upon reading the description and examples which follow.

[0020] Aminosilicone

[0021] The at least one aminosilicone chosen from formula (I) and (II) comprises:

[0022] wherein:

[0023] m and n are numbers with a sum (n+m) ranging, for example, from 1 to 1000 and further, for example, from 50 to 250 and still further, for example, from 100 to 200;

[0024] n is a number ranging from 0 to 999 and, for example, from 49 to 249 and further, for example, from 125 to 175, and m is a number ranging from 1 to 1000 and, for example, from 1 to 10, and further, for example, from 1 to 5;

[0025] R₁, R₂ and R₃, which may be identical or different, are chosen from a hydroxyl radical and C₁-C₄ alkoxy radicals, at least one of the radicals R₁ to R₃ chosen from alkoxy radicals.

[0026] The alkoxy radical may be, for example, a methoxy radical.

[0027] The hydroxy/alkoxy molar ratio may, for example, range from 0.2:1 to 0.4:1 and, for example, from 0.25:1 to 0.35:1 and further, for example, may be equal to 0.3.

[0028] The at least one aminosilicone of formula (I) may have a weight-average molecular mass ranging, for example, from 2000 to 1,000,000, for example from 3500 to 200,000.

[0029] wherein:

[0030] p and q are numbers with a sum (p+q), for example, ranging from 1 to 1000, for example from 50 to 350 and further, for example, from 150 to 250;

[0031] p is a number ranging from 0 to 999, for example from 49 to 349, and further, for example, from 159 to 239, and q is a number ranging from 1 to 1000, for example, from 1 to 10, and further, for example, from 1 to 5;

[0032] R₁ and R₂, which are different, are chosen from a hydroxyl radical and C₁-C₄ alkoxy radicals, at least one of the radicals R₁ and R₂ being chosen from alkoxy radicals.

[0033] The alkoxy radical may be, for example, a methoxy radical.

[0034] The hydroxy/alkoxy molar ratio may, for example, range from 1:0.8 to 1:1.1, for example from 1:0.9 to 1:1, and may further, for example, be 1:0.95.

[0035] The at least one aminosilicone of formula (II) may have a weight-average molecular mass ranging, for example, from 2000 to 200 000, for example from 5000 to 100,000, and further, for example, from 10,000 to 50,000.

[0036] The weight-average molecular mass of the at least one aminosilicone are measured by gel permeation chromatography (GPC) at ambient temperature in polystyrene equivalents. The columns used are μ Styragel columns. The eluent is THF and the flow rate is 1 ml/min. 200 μl of a 0.5% by weight solution of silicone in THF are injected. Detection is carried out by refractometry and UV metry.

[0037] An embodiment comprising the at least one aminosilicone chosen from formulae (I) and (II) may further comprise at least one aminosilicone whose formula may be different from the at least one aminosilicone chosen from formulae (I) and (II).

[0038] A product comprising the at least one aminosilicone of structure (I) is provided, for example, by the company Wacker under the name Belsil ADM 652®.

[0039] Products comprising the at least one aminosilicone of structure (II) are provided, for example, by the company Wacker under the name Fluid WR 1300® and Belsil ADM 6057®.

[0040] The at least one aminosilicone chosen from formulae (I) and (II) may be employed, for example, in an oil-in-water emulsion. The oil-in-water emulsion may further comprise at least one surfactant. The at least one surfactant may be chosen, for example, from cationic and non-ionic surfactants.

[0041] A particle of the at least one aminosilicone in the emulsion may have an average size ranging, for example, from 3 to 500 nanometres. Such particle sizes are measured with a laser granulometer.

[0042] The at least one aminosilicone of formula (II) may be used, for example, in an microemulsion. In the microemulsion, the at least one aminosilicone of formula (I) may have a size ranging from 5 to 60 nanometres and, for example, from 10 to 50 nanometres.

[0043] A microemulsion of the at least one aminosilicone of formula (II) may be available, for example, under the name Finish CT 96 E® or SLM 28020® by the company Wacker.

[0044] The at least one aminosilicone chosen from formulae (I) and (II) may be selected, for example, such that the contact angle with water of a hair treated with a composition comprising 2% AS (active substance) of the at least one aminosilicone ranges from 90 to 180°, for example from 90 to 130°.

[0045] A composition comprising the at least one aminosilicone chosen from formulae (I) and (II) may be such that the contact angle of a hair treated with the composition ranges from 90 to 180°, for example from 90 to 130°.

[0046] The measurement of the contact angle is based, for example, on the immersion of a hair in distilled water. The measurement consists of evaluating the force exerted by the water on the hair during its immersion in the distilled water and during its withdrawal. The forces measured are directly related to the contact angle θ between the water and the surface of the hair. The hair is hydrophilic when the angle θ ranges from 0 to less than 90° and hydrophobic when this angle ranges from 90 to 180°.

[0047] The test is carried out using locks of natural hair which have been bleached under identical conditions and then washed.

[0048] Each lock of 1 gram is placed in a 75 mm-diameter crystallizer and then covered homogeneously with 5 ml of the formula under test. The lock is left in this condition for 15 minutes at ambient temperature and then rinsed for 30 seconds. After being wrung out, the lock is left in the open air until completely dry.

[0049] For example, 10 hairs having undergone the same treatment are analysed. Each sample, fixed to a precision microbalance, is immersed by the end into a container filled with distilled water. This balance, which is a DCA (dynamic contact angle analyser) from the company CAHN Instruments, allows measurement of the force (F) exerted by the water on the hair.

[0050] The perimeter (P) of the hair is measured via microscopic observation. The average wettability force over 10 hairs and the cross section of the hairs analysed allow the contact angle of the hair with water to be obtained, in accordance with the following formula:

F=P*Γlv*cos θ

[0051] where F is the wettability force expressed in newtons, P is the perimeter of the hair, in metres, Γlv is the liquid/water vapour interfacial tension, in J/m², and θ is the contact angle.

[0052] For example, the product SLM 28020® from Wacker at 12% in water (i.e. 2% of at least one aminosilicone) gives a contact angle of 93° in the test indicated above.

[0053] The at least one aminosilicone chosen from formulae (I) and (II) may be used, for example, in a dyeing composition in an amount ranging from 0.01 to 20% by weight of the total weight of the composition. For example, this amount may range from 0.1 to 15% by weight, for example from 0.5 to 10% by weight.
